“Optimize all presets” broken on 26.10

Hi, I share many of the complaints of other users about the UI changes on the latest iOS update (especially the larger text making me scroll to see info that was previously available in a glance on the stats page, even in “compact” mode).

However, I’m also running into a new issue with the “Optimize all presets” button in FSRS settings. I now see a “TypeError: load failed” popup when I hit the button, before the “Processing” pop-up. In addition, the processing popup comes and goes very quickly, so it’s not clear to me if the FSRS parameters for all my decks are actually being optimized that quickly or if the TypeError is causing issues.

I’m on version 26.10. Thanks for your help.
